Description

A non-stop maintenance square filter cloth filter equipment

【Technical field】

The invention relates to sewage treatment filtering equipment.

【Background technique】

In the sewage treatment, the sewage first enters the sewage treatment tank through the pipeline. In order to improve the filtration speed of the sewage, there are multiple sumps at the bottom of the sewage treatment tank. Shuikou. After a long time of use, the filter cloth on the water inlet of the filter will be blocked by the stains in the sewage, and after a long time, a lot of sludge will be deposited in the sewage treatment tank, which will reduce the filter's ability to filter sewage, so it needs to be replaced frequently Filters, for this reason, bring a lot of workload to the staff, increase the cost of sewage treatment, and also affect the efficiency of sewage treatment.

In addition, after the filter cloth on the filter is blocked by the stains in the sewage, the filter needs to be replaced in time. When replacing the filter, it is necessary to close the water inlet valve of the sewage treatment tank first, stop the sewage from entering, and discharge the sewage treatment tank Remove the remaining sewage in the tank, then remove the filter, install a new filter at the same time or block the corresponding water inlet of the sump on the sump, and finally open the water inlet valve to introduce sewage for filtration. With this kind of open-opening structure of the sump, the filter cannot be replaced when the sewage is filtered normally, otherwise the sewage will directly enter the sump without being filtered by the filter, and the filtered sewage will be polluted again; if the filter is replaced , close the water inlet valve and stop filtering sewage, which will reduce the efficiency of sewage treatment and affect production.

The present invention studies and proposes a non-stop maintenance square filter cloth filter tank equipment aimed at the deficiencies of the prior art.
